Abstract

An optical image capturing lenses includes, in order from an object side to an image side, a front lens group, a stop, and a rear lens group. The front lens group includes, in order from the object side to the image side, at least a first lens element and a second lens element. The first lens element has a convex object-side surface and a concave image-side surface. The rear lens group includes, in order from the object side to the image side, at least a third lens element, a fourth lens element, a fifth lens element, and a sixth lens element. The sixth lens element is made of plastic material. The object-side surface and the image-side surface of the sixth lens are aspheric. The sixth lens element has at least one inflection point formed on at least one of the object-side surface and the image-side surface thereof.

RELATED APPLICATIONS

[0001] The application claims priority to Taiwan Application Serial Number 100130316, filed Aug. 24, 2011, which is herein incorporated by reference.BACKGROUND

[0002] 1. Technical Field

[0003] The present invention relates to an optical image capturing lenses. More particularly, the present invention relates to a compact optical image capturing lenses applicable to electronic products.

[0004] 2. Description of Related Art

[0005] In recent years, with the popularity of mobile products with camera functionalities, the demand for miniaturizing an optical image capturing lenses is increasing. The sensor of a conventional photographing camera is typically a CCD (Charge Coupled Device) or a CMOS (Complementary Metal-Oxide Semiconductor Sensor). As advanced semiconductor manufacturing technologies have allowed the pixel size of sensors to be reduced and compact optical image capturing lenses have gradually evolved toward the fields of higher megapixels, there is an increasing de...
